Mr. Bean crashed into middle of cement barrier (8)
I believe the answer is:
membrane
'barrier' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I don't see?
'mr bean crashed into middle of cement' is the wordplay.
'crashed' indicates an anagram.
'into' means one lot of letters goes inside another.
'middle of' means to look at the middle letters.
The middle letters of 'cement' are 'me'.
'mr'+'bean'='mrbean'
'mrbean' is an anagram of 'embran'.
'embran' inserted into 'me' is 'MEMBRANE'.
Can you help me to learn more?
(Other definitions for membrane that I've seen before include "Cell lining" , "Thin flexible film" , "Thin, pliable sheet of living tissue" , "parchment skin" , "Thin pliable sheet of material" .)
